Benchmark: ES6 Class vs Function with float32array vs Function with Array

Tests:

ES6 Class
class Point { constructor(x, y){ this.x = x; this.y = y; } add(point){ return new Point(this.x + point.x, this.y + point.y); } sub(point){ return new Point(this.x - point.x, this.y - point.y); } } var p1 = new Point(10, 10); var p2 = new Point(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Function float32array
function create_point(x,y){ return new Float32Array([ x , y ]) } function add_points(a,b){ return new Float32Array( [ a[0] + b[0] , a[1] + b[1] ] ) } function sub_points(a,b){ return new Float32Array( [ a[0] - b[0] , a[1] - b[1] ] ); } var p1 = create_point(10,10); var p2 = create_point(10,-10); var sum = add_points(p1,p2); var dif = sub_points(p1,p2);
Function array
function create_point(x,y){ return [ x , y ]; } function add_points(a,b){ return [ a[0] + b[0] , a[1] + b[1] ]; } function sub_points(a,b){ return [ a[0] - b[0] , a[1] - b[1] ]; } var p1 = create_point(10,10); var p2 = create_point(10,-10); var sum = add_points(p1,p2); var dif = sub_points(p1,p2);
